Allocate a relay channel to steer an air-conditioner
The temperature sensor can also be used to control an air-conditioning system. When the sensor is in cooling mode,
the heating will be switched to anti-freeze mode.
When room temperature rises above the desired value, a relay must be energised to switch on the air-conditioner.
When the temperature drops below the desired value the relay must be de-energized to stop cooling.
In this example relay channel 4 is used to steer the air-conditioner.
1. Set the sensor module in anti-freeze mode by
pressing the push button on the front panel
repeatedly until all LEDs are off.
2. Set the MODE and TIME1 rotary switches for
channel 4 of the relay module to ‘0’ (instant
control).
3. Remember the address of this relay module to
reinstate it later on.
4. Set the address of the relay module to ‘C4’. The
‘MODE 4’ LED flashes to indicate push button
learning mode (PBM).

5. Press and hold the upper push button (COOL) of
the temperature sensor until the relay is energised
and the red LED on the sensor module flashes.
6. Set the address of the relay module back to its
original value.
7. The sensor module must be placed in cooling
mode via the temperature controller VMB1TC or
through the Velbus link software. The upper LED
(ice crystal) must be lit.
